1 Piston RodGland seal life is maximized by manufacturing piston rods fromprecision ground, high tensile carbon alloy steel, hard chromeplated and polished to 0.2µm max.
2 Parker’s ‘Jewel’ GlandContinuous lubrication, and therefore longer gland life, areprovided by the long bearing surface inboard of the primaryseal. The Jewel gland, complete with rod seals, can easily
be removed without dismantling the cylinder, so servicing isquicker – and therefore more economical.
3 Rod SealsThe TS-2000 primary seal has a series of sealing edges whichtake over successively as pressure increases, providingefficient sealing under all operating conditions. On the return stroke the serrations act as a check valve, allowing the oiladhering to the rod to pass back into the cylinder.
The double lip wiperseal acts as a secondary seal, trappingexcess lubricating film in the chamber between the wiper and

lip seals. Its outer lip prevents the ingress of dirt into the cylinder, extending the life of gland and seals.
The TS-2000 is manufactured from an enhanced polyurethane,giving efficient retention of pressurized fluid and long service life.
4 Cylinder BodyStrict quality control standards and precision manufactureensure that all tubes meet rigid standards of straightness,roundness and surface finish. The steel tubing is surface finished to minimize internal friction and prolong seal life.
5 Cylinder Body SealsTo make sure that the cylinder body remains leaktight, evenunder pressure shock conditions, Parker utilizes pressure- energized body seals.
6 One-Piece PistonSide loading is resisted by the wide bearing surfaces of thepistons. A long thread engagement secures the piston to thepiston rod and, as an added safety feature, pistons aresecured by an anaerobic adhesive.
7 CushioningProgressive deceleration is available by using profiled cushions at the head and cap – see Section C for details.The head end cushion is self aligning, while the polished capend spear is an integral part of the piston rod.
8 Floating Cushion Bushings and SleevesCloser tolerances – and therefore more effective cushioning – are permitted by the use of a floating cushion sleeve at the head end of the cylinder, and a floating cushion bushing at the cap end. A slotted cushion sleeve at the head end and thefloating bronze cushion bushing in the cap, provide minimum fluid restriction at the start of the return stroke. This allows full pressure to be applied over the entire area of the piston,providing full power and fast cycle times.

Design Features and Benefits
9 Cushion AdjustmentNeedle valves are provided at both ends of the cylinder for precise cushion adjustment. 63 mm bores and smaller contain cartridge cushion assembly shown below.
Gland DrainsThe accumulation of fluid behind the gland wiperseal of long stroke cylinders, or cylinders with constant back pressure, can be relieved by specifying the option of a gland drain. A port between the wiperseal and primary seal allows fluid to be piped back to a reservoir. By fitting a transparent tube between the port and the reservoir, fluid loss from concealed or inaccessible cylinders can be monitored to provide an early indication of the need for gland servicing. Gland drains are described in greater detail in Section C of this catalog.
Parker Series HMI Metric Hydraulic Cylinders
Air BleedsAvailable as an option at both ends, the air bleeds are recessed into the head and cap.
Standard on 50mm bore sizes and larger, Parker’s B style piston is a single seal design which incorporates two wear strips. This design provides smooth operation, long bearing life, and high load carrying capacity.
Mixed Media Piston SealsFor applications requiring different media on either side of the piston specify Mixed Media Piston Seals with a W piston code. This option is ideal when hydraulic oil is on one side of the piston and air on the opposite side; and it can be equally effective when dissimilar fluids are on either side of the piston. Superior low-friction bi-directional sealing is accomplished by combining an energized filled PTFE seal with a redundant elastomer seal.
Servo CylindersServo cylinders permit fine control of acceleration, velocity and position in applications where very low friction and an absence of stick-slip are required. They may be used in conjunction with integral or external transducers. Servo cylinders combine low friction piston and gland seals with specially selected tubes and rods. For low-friction applications – consult factory.
Seal ClassesTo accommodate the many types of fluids and the varying temperature ranges used in industry, Parker offers a range of rod gland, piston and body seals. These are described in detail in Section C of this catalog.
Piston Seals Standard on 25mm, 32mm and 40mm bore sizes, Parker’s Lipseal™ Piston provides zero leakage under static conditions for hydraulic pressures up to 3000 psi. Seals are self-compensating to conform to variations in pressure, mechanical deflection, and wear. Back-up washers prevent extrusion.

Mounting Styles
ISO Cylinder Mounting Styles and Where to Find ThemThe standard range of Parker Series HMI cylinders comprises 12 ISO mounting styles, to suit the majority of applications. General guidance for the selection of ISO cylinders is given below, with dimensional information about each mounting styleshown on the following pages. Application-specific mounting information is shown in the mounting information section, Section C of this catalog.
Extended Tie Rods Cylinders with TB, TC and TD mountings are suitable forstraight line force transfer applications, and are particularlyuseful where space is limited. For compression (push)applications, cap end tie rod mountings are most appropriate;where the major load places the piston rod in tension (pull applications), head end mounting styles should be specified. Cylinders with tie rods extended at both ends may be attachedto the machine member from either end, allowing the free endof the cylinder to support a bracket or switch.
Flange Mounted CylindersThese cylinders are also suitable for use on straight line forcetransfer applications. Two flange mounting styles are available, offering either a head flange (JJ) or a cap flange (HH). Selec-tion of the correct flange mounting style depends on whether the major force applied to the load will result in compression(push) or tension (pull) stresses on the piston rod. For compression-type applications, the cap mounting style is mostappropriate; where the major load places the piston rod intension, a head mounting should be specified.
Foot Mounted Cylinders Style C, foot mounted cylinders do not absorb forces ontheir centerline. As a result, the application of force by thecylinder produces a moment which attempts to rotate thecylinder about its mounting bolts. It is important, therefore, that the cylinder should be firmly secured to the mounting surface and that the load should be effectively guided to avoid side loads being applied to rod gland and piston bearings. A thrustkey modification may be specified to provide positive cylinder location.
Pivot Mountings Cylinders with pivot mountings, which absorb forces on theircenterlines, should be used where the machine member tobe moved travels in a curved path. Pivot mountings may beused for tension (pull) or compression (push) applications. Cylinders using a fixed clevis, styles BB and B, may be used if the curved path of the piston rod travel is in a single plane; forapplications where the piston rod will travel in a path on eitherside of the true plane of motion, a spherical bearing mountingSB is recommended.
Trunnion Mounted Cylinders These cylinders, styles D, DB and DD, are designed to absorbforce on their centerlines. They are suitable for tension (pull) or compression (push) applications, and may be used where the machine member to be moved travels in a curved path in asingle plane. Trunnion pins are designed for shear loads onlyand should be subjected to minimum bending stresses.

How to Order ISO CylindersData Required On All Cylinder Orders
When ordering Series HMI cylinders, be sure to specify each of the following requirements:
(NOTE: – Duplicate cylinders can be ordered by givingthe SERIAL NUMBER from the nameplate of the original cylinder. Factory records supply a quick, positiveidentification.)
a) Bore Size
b) Mounting Style Specify your choice of mounting style – as shown and dimensioned in this catalog. If double rod is required, specify with double rod.
c) Series Designation (“HMI”)
d) Length of Stroke
e) Piston Rod Diameter Call out rod diameter or rod code number. In Series HMI cylinders, standard rod diameters (Code No. 1) will be furnished if not otherwise specified, unless length of stroke makes the application questionable. f) Piston Rod End Thread Style Call out thread style number or specify dimensions. Thread style number 4 will be furnished if not otherwise specified.
ADDITIONAL DATA is required on orders for cylinders with special modifications. For further information, consult factory.
g) Cushions (if required) Specify Cushion-head end, Cushion-cap end or “Cushion-both ends” as required. If cylinder is to have a double rod and only one cushion is required, be sure to specify clearly which end of the cylinder is to be cushioned.
h) Piston Parker B style pistons are standard. Fluorocarbon also available. i) Ports BSP (ISO 228) are standard.
j) Fluid Medium Series HMI hydraulic cylinders are equipped with seals for use with hydraulic oil. If other than hydraulic oil will be used, consult factory.
Service PolicyOn cylinders returned to the factory for repairs, it is standard policy for the Cylinder Division to make such part replace-ments as will put the cylinder in as good as new condition.Should the condition of the returned cylinder be such thatexpenses for repair would exceed the costs of a new one, youwill be notified.
Address all correspondence to Service Department at yournearest regional plant listed in the pages of this catalog.
Certified DimensionsParker Cylinder Division guarantees that all cylindersordered from this catalog will be built to dimensions shown.All dimensions are certified to be correct, and thus it is not necessary to request certified drawings.
